BITSAT 2021 | Work, Energy and Power Question 2 | Physics

A force F = a + bx acts on a particle in the x-direction where a and b are constants. The work done by this force during a displacement from x = 0 to x = d is

$$\left( {a + {{bd} \over 2}} \right)d$$

$$\left( {ad + {{bd} \over 2}} \right)$$

$$\left( {{{ad + bd} \over 2}} \right)$$

$$(ad + b){d \over 2}$$
